To all whom it may concern:

Be it known that we, Tuooms J. CARRI- can, Jon}: B. ltis'rimx, and MATTHEW E.

Macnm, all citizens of the United States, the two former residing at Los Angeles, in theof meat are not as desirable as others by reason of the fact that such portions of meat wntain a'great deal of fibrous or tough material. hrealdng down or cuttimr he shim-s or fiber, such cuts of meat are rendered more desirable. It frequently happens that in meats of this class there may occur portions of bone, or other hard substance, which might seriously damage the cutting elements of the machine, unless provision were made against such occurrences, and one of the main objects of our invention to produce a machine of the class described of simple form and construction in which the cutters are arranged in groups, each group being separately elastically held in the cutting position.

(lther objects and advantages will appear.

hereinafter from the following description. Referring to the drawmgs, wh1ch are for illustrative purposes only:

Figure l is a front elevation of a machine embodying a form of our invention,

the front door being raised t6 show the inof the machine.

'lflllWflS shownin relation thereto.

Fig.6 is a frontclevation of a portion of one end of the driving shaft, showing the parts of the machine in section.

The machine comprises atablc l0 horizontally disposed and supported'on legs 11 which form extensions of side walls 12, the side Walls being connected at their upper portion by a tooor cover 13 which may be secured to the side walls in any suitable manner, or formed as a part thereof.

14, 14: designate brackets secured to the side walls 12 by means of suitable bolts 15, in which brackets is journalcd a shaft 16, said shaft being provided with cranks 17. Mounted upon each crank 17 is a connecting rod 18 formed in two parts 19 and'20 which! are adjusted with relation to each other by means of a threaded bolt 21 having a knurled nut 22 thereon to fac litate such adjustment.

25 designates a cutter frame which termi: nates at each end in rearwardly extending arms 26, which arms 26 are-pivotally mounted on a shaft 27 mounted 1n the respective side walls 12. The arms 26 on the cutter frame 25 are pivotally connected as indicated at 28- to the upper ends of the connecting rods 18.

30, 30 designate a series of spring arms pivotally mounted at their rear ends on the shaft 27 and being held in engagement with the upper face of the cutter frame 25 at their outer ends by means of a U-shapcd spring member 31 having coils 32 intermediate its length, which coils engage studs 33 mounted on the spring arms 30. The upper, end of the spring 31 is engaged by a hook at mounted on thecutter frame 25 and extends upwardly through a hole 36 formed in the spring arm 30. The opposite end of each spring 31 extends forwardlyand is sccuredin any suitable manner in the spring arm, the action of the spring being to clastically hold the spring arm seated upon the upper face of the cutter frame.

38, 38 designate a-series of cutter heads, each spring arm 30 being provided with a cutter head which is secured to the face or outer end of the respective spring arms 30 by means of a threaded bolt 39 having a suitable head 40 for operation ,of the bolt. Each spring arm 30 is provided with an outwardly extending flange or li-p 4:1 along its upperfront edge under which the upper 42, d2 designate a'series of cutting blades sharpened at their lower ends and terminattially an angle-bar in cross section, one end of which terminates in a flat member 45 which extends in a socket t6 formed on one of the side walls of the machine, the other end of the stripper plate being provided with a pin 47 which extends into an opening formed in a spring plate 48 secured in any suitable manner to the opposite side wall of the machine, there being a number of openings 49 in the spring plate 48 and a corresponding number of sockets formed in the plate 50 on the opposite wall of the machine.

1 designates a wire guard. the ends of which are secured in any suitable manner to the stripper plate 44, the guard being provided with two outwardly bent portions forming handles 52.

53 designates a wooden table provided at its forward end with a handle 54 and is adapted to ride on tracks 55 formed on the table 10.

56 designates a rack secured to the under face of the cutter frame which is adapted to be engaged by a dog 57 which operates through an opening 58 in the table, and which is pivotally mounted on the for ard end of a slidably mounted rod 59 supported in brackets 60 and 61 on the lower side of the table.

62 designates a coiled spring on the rod 59 which abuts at one end against the bracket 61 and at the other end against a flange 63 formed on the rod 59. y

64 designates a coiled spring, one end of which is secured to the bracket 60 and the other end is secured to the rod 59, the tension of the spring being to pull the rod 59 downwardly so that the dog 57 is out of engagement with the rack 56.

leans are provided for positively raising the rod 59 which consist of a cam 65 formed on the shaft, a cam 66 also on the shaft being provided to engage a roller (37 on the rod 59 to move the rod rear *ardly when the dog 57 is in engagement with the rack 56. To preventl'ireaking of the dog 57, which might occur should the dog strike a tooth on the rack, instead of between the teeth, the dog 57 is pivotally mounted on a pin 68 on the rod 59. A spring 69 is mounted on the pin 68, one end of which engages a stud 70 on the rod 59, and the other end of the spring engages under the dog, thereby terdin to elastically hold the dog in raised )OSllZIQIl.

The stud 70 extends through a slot 71 formed in the dog 57 and thereby limits the movement of the dog on therod.

T5 and 76 represent front and rear doors which are hinged or movably attached to the cover 13, as indicated at 77, these doors being-closed, as shown in the full line position in Fig. 2, when the machine is not in operation, and being raised into the dotted line position'shown in Fig. 2 when the machine is in operation.

The machine is opertited in the following manner:

The table 53 is drawn forwardly into the position shown in dotted lines in Fig. 2 and the meat, such as a steak, placed thereon, after which the machine is set in motion by operation of the handle 80 on a fly wheel secured to the end of the shaft 17. The shaft being rotated, a reciprocating motion is transmitted to the cutter frame 25 through the medium of the connecting rods 18. The cutter frame 25 during such movement carries with it the spring arms 30, the (utter heads 38, and the knives 42, the respective spring arms 30 being yieldingly held seated on the cutter frame by means of the springs 31. This reciprocating movement of the parts just described causes the knives to en: ter the meat on the table 53 penet ate the same, during which operation the sinews or fibrous material in the meat is broken up by a series of cuts made by the knives 42. When the knives are in the lower position shown in Fig. 2, the dog 57 has just engaged the rack 56 on the lower face of the table 53, the dog being raised into engage-- ment with the rack by means of the cam (i5 engaging under and raising the rod 59. As the knives 42 move upwardly. the. cam (it comes into engagement with the roller 67 on thejrod 59 and moves the rod 59 rcarwardly, thereby causing the cam 59 to move the table and meat thereon forwardly into the ma chine in position to receive the knives into another portion of the meat. After the cam 66 passes from engagement with the roller 67, the spring 62 on the rod 59 moves the rod 59 forward to its original position, the cam. 65 having permitted the rod 59 to drop and the dog 57 to come out of engagement with the rack 56. In the event that the knives should strike a hard substance, such as bone, the cutter head 38 carrying'such knives is permitted to move upwardly elastically agaipst the action of thespring 31 on. the spring arm 30 to which such cutter head is attached, thereby permitting the balance of the knives to perform their work of cutting the sinews in the other portions of the meat. The stripper plate 4H may be readily re moved from the machine by grasping the handle or handles 52 and moving the plate sidewise out of engagement with the sockets in the plate 50, which action is permitted by and partially Tim messes virtue ot the opposite end of the stripper plate being mounted in the spring plate 48.

It is understood that the machine is operated until the meat has entirely passed under the cutters, after which the table ing a table, a support for said table, a meatboard slidahly mounted on the table, a cutter frame pirotally mounted on said support, a series of arms pivotally mounted on said support, means for elastically holding said arms on said frame, a head removably mounted on each a-rm, a series of knives mounted in each of said heads, and means for imparting a substantially vertical reciprocating movement to said frame.
